Keyless ignition system is one of the features available in top variants of all the popular cars in the Indian market. First introduced by Mercedes-Benz back in 1998, it has become a widely popular feature in cars across the world. But, a recent study has revealed that idling cars with keyless ignition has caused 28 deaths in United States of America. Also, carbon monoxide poisoning from such cars have caused major injuries including brain damage for 45 people.

As the study reveals, many owners forgot to turn off the engine after parking their vehicles in closed space. This forgetfulness could be attributed to the near-silence of the modern cars when they are idle. When the engine runs for long time in idle mode, the exhaust fumes containing carbon monoxide fill the area. Such situation could be lethal.

Auto manufacturers have been asked by the Society of Automotive Engineers back in 2011 to install audible or visual alerts for the drivers to turn off the engine before leaving the vehicles. Now, as the data related to the deaths caused by the carbon monoxide poisoning involving idling cars with keyless ignition has came forward, the National Highway Traffic Safety Administration is expected to bring some regulation changes for the automakers.

While several automakers have already opposed the idea citing the reason of increased cost, Ford and some other brand have added a feature to alert the drivers to turn off the engine when the car is idle for some time and the key fob is not in the vehicle. We would suggest our readers to stay alert and turn off the engine when you leave your vehicle, as this will save precious fuel and minimize emission. Also, more importantly, this little cautiousness will save you from possible danger.
